To all whom it may concern.-

Be it known that we, Momus KAssnR and Josnrr-r B. 'IQASSER, citizens of the United States, residing in the city andcounty of San Francisco and State of California, have invented anew and useful Improvement in Compartment-Inflatersfor Ships, of which the following isa specification.

Our invention relates to compartment inflaters for ships and the like wherein a con tainer of compressedair within each compartment operatesin conjunction with a collapsible bag therein and with'a float valve arranged to inflate thebagwhen the said compartment is flooded; and the objects of our invention are first, to provide improved means for finflatinglthe compartment of a ship when the same is in danger of being flooded; second, to provide improved'means for supplying a container of compressed air to each separate compartment; third, to provide improved means for detaching and renewing a compressed air retainer; fourth, to provide improved means for normally retaining the compressed air within the container; fifth, to provide improved means for automatically retaining the container in connection with the inflating means; sixth, to provide means visible from Without the container to indicate the amount of compressed air within the container; and seventh, to provide a separate independent means for inflating each separate compartment.v

We accomplish. these several features by means of the device disclosed in the drawings forminga part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, andin which Figure 1 is a brokenhorizontal sectional view of a ship disclosing'the manner in which the same is provided with separate compartments. Fig. 2 is a broken side elevationof Fig. 1. Fig. 3 is a vertical sec tional view of one of the compartments dis,- closing the inflating mechanism therein in a collapsible condition. Fig. dis a view similar to Fig. 3 but disclosing the inflating mechanismin an inflated position. Fig. 5 is a broken sectional'front view of the inflating mechanism. Fig. 6-is a" vertical sectional view of the valve housing within each compartment disclosing the manner in Which the container is detachably secured within the compartment andthe manner in which the check valve therein is retained in an open position. .Fig. 7 is a view similar to Fig. 6 but with the container and valve housing shown slightly separated and the check valve closed. Fig. Sis a broken front elevation of the valve housing disclosing the threaded aperture and the arrangement of the cup shaped valve. Fig. 9'is a rear end elevation of one of the containers disclosing the pressure gage secured thereto.

Referring to the drawings, the numeral 1 isused to designate the outer hull of a ship or vessel and Q'an inner or false hull or wall; The space between the outer wall 1 and the inner wall 2 is separated into compartments bymeans of the vertical and horizontally 'rotatably mounted a cup-shaped valve 6.

The threaded aperture 7 is arranged to engage a threaded extension 8 ofa compressed air container 9 having a check valve 10 slidably mounted therein and arranged to be normally held to a valve seat 11 by means of a suitable spring 14 operatively connected to the stem 12 of the said valve 10.

hen the extension 8 of the container!) is'secured within the threaded aperture? of the valve housing 6, thevalve 6 therein will engage the stem 12 of the valve 10 and retain the same in an open position against thetension of the spring 14- as disclosed in Fig. 6 of the drawings.

The valve 6 is provided with a port 18 arranged to register, in one position, with a channel20 of thehollow extension 22 of the valve housing 5.

- Secured to'the hollow extension 22 is a collapsible bag 25 arranged to lie in a collapsed state in the bottom of the compartment so that should the said compartment be punctured or injured above the bag, the

latter will not thereby be injured.

The cup-shaped valve'6- is provided with a stem 26 to which is rigidly secured a'lever 27 having a suitable float 28 thereon, In order to hermetically seal the compartment wlien'the container 9 is secured therein, we have provided an annular flange 30'on the outer'end of the said container 9, said annular flange 30 being arranged to press the surface of the inner wall'2 adjacent" to the aperture therein through which the container 9 is inserted. A suitable gasket 31 is provided between the said annular flange 30 and the inner wall 2. I

The outer end of the container 9 is provided with a recess 16 within which is secured a suitable pressure gage 17 connected to the interior of the said contalner 9 so that outer wall 1 of the compartment be punctured and water admitted thereto, the presence of the water will raise the float 28 and cause the port 18 of the valve 6 to register with the channel 20 within the extension 22 to which the collapsible bag 25 is secured or connected. Inasmuchas' the check valve '10 is retained in an open position by the valve 6 which engages the'stem 14 it is evident that the compressed air will be released from the container 9 and will flow intothe bag 25 and thereby cause the said bag to expand and inflate the compartment. 1 The pressure of air within the container is designed to be of sufficient pressure to inflate the to such an extent that any water .Within'the compartment will be forced there from. Inasmuch as the flange 3 0 of the container 9' is tightly held against the inner wall 2 by means of the threaded aperture 7 of the housing 5, which engages the threadedextension 8 of the said container 9, itis evident that the'water cannot'e'nter the in terior of the ship. After the compressed air has been released from a container 9 into a bag 25 the location of the compartment inflated or the location of the damage to the ship, may be readily determined by consulting all of the pressure gages. That gage showing a decrease in pressure will indicat the location of the trouble. 7 7

It is obvious from the foregoing that we have provided improvedm'eans for auto matically inflating a punctured compartment of a ship,Iand also separate independent means for, automatically inflating each separate compartment, so that in the case of a sailing ship where, there is no available" machinery aboard for pumping or compressing air,- the compartments may be easily and automatically inflated. Also should one inflating mechanism for one compartment be disabled, it will not -afi'ect, the other com- 'partments, the containers being easily remov'ablemay be easily replaced when: eX-

hausted. c. m e x Having. thus described our invention what we claimasnew and desire to secure by Let 11,. A ship having compartments, each of the compartments being provided with an pening'jn one wall; a valve casingwithin the compartment and alined with the opening; a collapsible bag connected to the valve casing; a valvein the casing to control the passage of gas therethrough to the bag; a

ceptacle; a collapsible bag connected to the valve casing; a valve in thevcasing to con- .trol the passage of gas therethrough to the bag and adapted toopen the check valve within'the compressed air receptacle; and a float to control suchpassage when the compartment is flooded.

' .3. As'hip having compartments, each of the compartments being provided with an Y opening in one wall a compressed air'receptacle inserted through said opening and having a normally closedcheck valve therein; a valvecasing within thecompartment alined with the opening therein and adapted toconnect with the compressed air receptacle; a collapsible bag connected to the valve casing; a cup-shaped valvewithin the casing-to control the passage of gas there through and adapted toopen the check valve 7 within the compressed air receptacle; and means adapted to control the cup shaped valve to permit such passage when the compartment is flooded r 4. A ship having-compartments, each of the compartments being provided with an opening in one wall; a compressed air rehaving a 'normally closed check valve therein; a valve casing within the compartment and alined with the opening and adapted to connect with the compressed air receptacle ceptacle'inserted through said openingand and to retain'thesaid receptacle within the compartment; a collapsible bag connected to the valve casing; a cup-shapedvalvewithin the I casing to control the passage of gas therethrough and adapted. to open the check valve within the compressed air receptacle;
